Tips to Help You Prepare for HEDIS MY 2025 Reporting
November 5, 2025 · NCQA Communications
Although the calendar year is ending, reporting activities for HEDIS® MY 2025 are just getting started, and will continue into next year. Keep these tips in mind as you prepare.
Know Your MY 2025 Reporting Requirements
Health plans report HEDIS for many reasons, including for participation in public and private quality programs. Most programs have released their MY 2025 measure sets. For example, CMS released Medicare Advantage HEDIS requirements in June, and NCQA released the latest Health Plan Ratings methodology in October. Organizations should be familiar with the requirements.
Remember that measure specifications might have changed for MY 2025. Refer to HEDIS MY 2025: What’s New, What’s Changed, What’s Retired for a summary of changes. Updates may include changes to the data collection methodology (e.g., Childhood Immunization Status transitioned to ECDS reporting), or to the population assessed (e.g., Breast Cancer Screening lowered the screening start age from 52 to 42 years).
Understanding the technical specifications and referencing the predictive trending determinations can provide insight when evaluating preliminary MY 2025 rates.
Prepare for the HEDIS Compliance Audit™
All health plans reporting HEDIS MY 2025 must participate in a HEDIS Compliance Audit™. All licensed organizations and Certified HEDIS Compliance Auditors must follow a standardized methodology and provide an independent assessment of information systems, data management processes and final HEDIS rates. Auditors are not allowed to provide technical assistance or advisory services; their strict independence is what makes an audited HEDIS result trusted for public use.
The HEDIS Roadmap for the audit was released in September, and health plans should be working to meet the upcoming audit deadlines. Mark your calendar for these key 2026 dates.
| January 30 | February 27 | March 27 | April 10 | May 1 | May 22 |
|---|---|---|---|---|---|
| Roadmap due, survey sample frame validation complete. | Nonstandard supplemental data collection ends. | All supplemental data validation must be completed. | Submit preliminary rates through IDSS. Early rate review is highly encouraged. |
Medical record abstraction ends. | Medical record review validation complete. |

Stay on Top of Data Submission Deadlines
A successful HEDIS submission starts with completing the Healthcare Organization Questionnaire. The online system opens in early December; health plans must submit their HOQ before the system closes on February 6, 2026.
The IDSS opens in March. Health plans should load data early to address system warnings and errors. All plan-locked data are due by Monday, June 1, 2026. An authorized representative must attest to the data as part of the final submission.
HEDIS MY 2025 reporting ends Monday, June 15, 2026, at 9:00pm (ET). Don’t wait until the last day to submit results! (Most organizations submit results early—only 2% were received on the final day for HEDIS MY 2024.)
